Tonight my series 3 has developed a slight tapping noise from the top end. Checked injectors and the noise doesn't go when they are cracked off.
Can anyone give me any ideas before an internal investigation is carried out?
Thanks in advance
 
Tappets? I had a weird tapping sound and it turned out to be one the injectors leaking very slightly. See if you can narrow the area down.
 
A well known issue with those engines are the prechambers. If they come out of position they will make a tapping sound. When this happens, you should not drive any longer, or your engine will be ruined.
